Wartime Leather Helmet By Spalding 1942, Motorcycle? For Sale

Wartime Leather Helmet by Spalding 1942, Motorcycle? The Helmet is a size 7 and has a C with an arrow stamped in Ink Which I think means it was used by the Canadian Armed forces. It has leather flaps lined with blue cloth. It is in excellent clean condition and was used very little. I really don't know what is was used for? Any ideas?
